Patients on warfarin may have decreased protein C levels. Warfarin therapy should be discontinued for at least two weeks prior to protein C testing. Decreased concentrations of protein C are also associated with liver disease, vitamin K deficiency, acute thrombosis, and DIC. Increased protein C concentrations may be observed in nephrotic syndrome, pregnancy, and with estrogen therapy.
